Stop in for a cup of coffee

Did not know about the tube until after i did the water pump and installed rad. Cdn models use a brass tube,and typically they dont fail. But its on my list to check. I figured the slant 6 rad would be enough. I think its blocked,more crud probably floated up out of block and into rad. Have to pull it to check.
When I rebuilt the engine in my truck, I knocked out the freeze plugs and the crap in the block was over half way up the plug. I had the block vatted, and I still had to stand the block “upside down” and flush it more with the pressure washer. Amazing how much crap was in there.
